The earth is warming at a steady pace and is having a devastating impact on the earth’s climate. Climate change is mostly natural. However, clear evidence exists that the rate of the occurrence of the changes we are experiencing in the climate and the intensity of the impacts are closely related to human activity. We understand the reason for this is the increase in human-caused greenhouse gases causing more warming of the earth's climate. How much have humans contributed to the greenhouse gases and what is the contribution of humans to climate change is still a global discussion. The presentation will focus on what climate change is, where we have come from and where we are going with the level of human influence. A debate on whether climate change mitigation is a moral or political issue will also be opened.
